6 Claims.

having their channeled sides presented inwardly and receiving in their channels the ends of the (usually wooden) top and bottom rails of the frame, the ends of the bars being usually bent inwardly at right-angles and secured to the rails outwardly thereof as by screws. This construction has this fault, that the heddles at each end of the series thereof are likely to worky into the channels of the side bars not only when the frame is in use in the loom but at the time the heddles are threaded in the operation known as entering the warp. According to this invention I retain the said channeled form of the side bars and at the same time avoid the mentioned fault, besides incidentally further reinforcing the frame.

In the drawing:

Fig. 1 is a front elevation of the improved frame, showing heddles therein;

Fig. 2 is a fragmentary elevation of .the frame on a larger scale, the side bar and a certain strip being shown partly in longitudinal section;

Fig. 3 is a fragmentary end elevation;

Fig. 4 a section on line 4 4, Fig. 2; and

Figs. 5 and 6 are sections on lines 5 5 and 6 6 respectively, of Fig. 3.

l designates the top and bottom rails and 2 the side bars each formed of a channeled metal strip having its ends 2a bent olf on its channeled side at right-angles so as to embrace the outer corner of the corresponding rail, which is fitted into the channel of the strip, 3 being screws entered through holes in said ends of the strip and tapped into the rails.

In order to prevent the heddles a from having access to the channels of the side bars and augment the reinforcing thereof which is an incident of their channeled form I provide metal strips 4 which in the example are shaped and secured as now to be stated: Each strip Li is initially somewhat longer than the distance between the rails l and it has its terminals da bent ofi at right angles. Its mid portion 4b is offset with respect to its end portions 4c (having said terminals fia) as by bending the strip so as in effect to form an arch, such arch projecting in the same direction as the terminals fia; the extent of offset of the portion 4b with respect to the portions 4c is about equal to the depth of the channel of the side bar. This strip is arranged in the channel and so as to extend lengthwise of the side bar and is secured by rivets 5 passed through its end (c1. isa-aa)y portions Lic and the side bar, and said portions :le bear against the bottom of the channel, wherefore its portion lib will stand about flush with the edges of the side bar flanking the channel. The length of each strip between its bent- 5 oli terminals la is such that in the assembled relation of the side bar and strip the ends of the rails may be snugly fitted between such terminals and the ends 2a of the side bar and thereupon said terminals secured to the rails by screws S. 10

l designates heddle bars on which the heddles are strung and which penetrate holes 8 formed in the side bars and strips 4; l5 designates the usual spring hooks which are engaged in holes in the protruding ends of the heddle bars and hold them taut, having rebends engaged in holes S formed in the side bars and strips 4; and l I designates rods which are mounted in eyes l2 secured to the rail l and on which are strung hooks I3 engaging with and thus supporting the heddle bars against exing under the load of the heddles.

In the example herein set forth the strips 4 obviously directly reinforce the side bars to which they are directly attached, as by rivets 5, at points more or less remote from each other, and they obstruct entry of the end heddles in the series to the channels of the side bars, so that the complete series stands at all times clear. The arches of the strips i are preferably formed of such appreciable extent and so located (midway between the rails) as to prevent the end heddles, even if they assume a somewhat tilted position as far as the heddle-bars will permit, from becoming housed in the channels for a more or less partial extent thereof.

I claim:

l. The combination, with the hereindescribed structure including top and bottom horizontal rails, side bars connecting the rails and one having an inwardly open channel, and means on 40 which the heddles are shiftable parallel with the rails, of a metal strip secured to said structure within the channel of the channeled side bar and having end portions bearing against the bottom of said channel and anV intermediate portion thereof offset from such bottom, said intermediate portion obstructing entry of the heddles into the channel.

2. The combination, with the hereindescribed structure including top and bottom horizontal rails, side bars connecting the rails and one having an inwardly open channel, and means on which the heddles are shiftable parallel with the rails, of a strip secured to said structure within the channel of the channeled side bar and having portions one of which bears against the bottom of the channel and the other of which is offset from such bottom and obstructs entry of the heddles thereinto, the rst named portion having a bent-01T terminal bearing against the relatively inner side of one of said rails.

3. The combination, with the hereindescribed structure including top and bottom horizontal rails, side bars connecting the rails, and means on which the heddles are shiftable parallel with the rails, of a metal strip extending lengthwise of a side bar and having its end portions secured thereto and its intermediate portion forming a relatively long arch.

4. The combination, with the hereindescribed structure including top and bottom horizontal rails, side bars connecting the rails, and means on which the heddles are shiftable parallel with the rails, of a metal strip extending lengthwise of a side bar and having its end portions secured thereto and its intermediate portion forming a relatively long arch, said end portions having bent-oi terminals bearing against the inner surfaces of the rails. Y

5. In combination, with a heddle frame `proper including top and bottom horizontal rails and channeled metal side bars connecting and 6. In combination, with a heddle frame proper including top and bottom horizontal rails and channeled metal side bars connecting and abutting the ends of the rails and having their channels open inwardly, and with means in the frame proper on which heddles are shiftablev parallel with the rails, of a slender metal strip secured to the frame proper within the channel of a side bar and having end portions bearing against the bottom of said channel and an intermediate portion thereof offset from such bottom and obstructing entry of the heddles into the channel, said strip having bent-off terminals bearing against the relatively inner sides of the rails.
